LUBRICAT OR.

SPECIFICATION forming part of Letters Patent N 0. 725,545, dated April 14, 1903. Application filed May 1, 1902. Serial No.105,514. (No model.)

To all whom it may concern:

Be it known that I, EDWARD E. DAVIS, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Lubricators,of which the following is a specification.

My invention relates to lubricators, and has for its object to provide a dash-feed oilcup adapted to be applied to a shaft or other moving part of machinery and having its feed effected by the motion of such machinery and having an auxiliary capillary feed device acting during the stoppage of the machinery to supply oil to the part to be lubricated in sufficient quantity to serve for the lubrication required in starting up the machinery again. I

To these ends my invention consists of the means hereinafter described and claimed.

My invention is illustrated in the accompanying drawings, in which Figure l is a central vertical sectional view of my improved oil-cup; Fig. 2, a top plan View, and Fig. 3 a detail of wick-supporting wire.

Referring to the drawings, the body a of the oil-cup is of the ordinary hollow cylindrical-form, provided with the stud b for attachment to the part to be lubricated. An

oil-passage extends through this stud and up through a feed-tube a, rising from the center of the inner base of the cup and formed in the post 01. This stem is open at the top to admit oil dashed from the body of the cup by the motion of the machinery. The post d is thickened toward one side, as shown in the.

carried by and held in proper position within the reservoir and. feed-tube by a support or holder g, consisting, preferably, of a single piece of wire made in the form shown in Fig. 3. The holder comprises a short leg 71 and a This part is 7 long leg 2', extending, respectively, into the reservoir and feed-tube, and the ends of the legs being bent to formthe respective loops j 70, through which are passed the ends of the wick. The shortleg of the wire extends up through the reservoir and is bent at a right angle and then doubled uponitself, so as to extend horizontally and form the straight bearing-arm Z. At one end'ofi the arm Z,above the feed-tube, thewire is bent'into an eye m, which bears upon the cut-away prolonged part of the post. .The bearing-arm Z is on a line with the upper end of the wall of the feed-tube. The wick is adapted to be passed through the loop of the shorter leg up the reservoiraud overthe bearing-arm and then through the eye 'm and down the feed-tube and through the loop 70. The wick is thus held by the wire inv proper position within the reservoir and tube.

The wire is held in proper position and prevented from being shaken or jarred out of the reservoir by. the pressure of a part inserted within the cup, preferably by the cover 01.

itself, upon the bearing-arm Z of the wire.

The cover is threaded and screwed within the threaded upper part of the body. A fillingplugp screws into the cover it. s v

The operation of the device is as follows:

'The wick and holder being placed in position,

the washer and cover are screwed down, the latter so as to bear upon the wire, and the cup then supplied with oil and the fillingplug p screwed into place. When the shaft or other part of machines on which the cup is mounted is put in motion, the oil will be dashed up and into the feed-tube c and the reservoir c and will be fed down the tube to .the part to be lubricated. When the ma-- chinery is stopped, the positive dash-feed of parting from the scope 'of my invention.

Having thus described my invention, what I claim is-- l. A lubricator consisting of a dash-feed cup provided with an open feed-tube, an open reservoir in said cup, and a wick leading from said reservoir to the feed-tube, substantially as described.

2. A lubricator consisting of a dash-feed oil-cup, having a feed-tube, a separate reservoir in the cup, and a capillary feed device leading from the reservoir to the tube, substantially as described.

3. A lubricator having an oil-containing cup, an auxiliary oil-reservoir in said cup, a feed-tube, awick-holder consisting of a frame extending into the reservoir and tube, and a wick havingits ends held by said frame, substantially as described.

4. A lubricator having an oil-containing cup, a feed-tube, a Wick, a Wick-holder consisting of a frame having a part extending down into the tube and having the end of the wick secured thereto, said frame having an arm above the tube and a member bearing against said arm to hold the frame in place, substantially as described.

5. In a lubricator having an oil-containing cup, a feed-tube, an auxiliary reservoir in the cup, a wick, a wick-holder consisting of a frame having legs extending into the reservoir and feed-tube, loops at the ends of the legs to which the wick is attached, a bearingarm at the upper part of the tube, and an eye through which the wick passes, and means to bear upon said arm, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD E. DAVIS.
